Trieste, the city of Umberto Saba and Italo Svevo, is a crossroads of culture and religion, both due to its geographical position on the "border" and the ups and downs of history that have made it a meeting point for many peoples. The Miramare castle is beautiful, overlooking the Gulf of Trieste, a few kilometres north of the city, and was commissioned by Maximilian of Habsburg, Archduke of Austria and Emperor of Mexico and was later the home of the Duke Amadeus of Aosta. It is also worth visiting the giant cave in the Trieste Karst, the plateau behind Trieste.  The view is impressive due to the exceptional proportions of the cavity and the skilful illumination that highlights everything nature has created.
